Objects of this struct may be obtained with <span class="t-lc"><a href="localeconv.html" title="c/locale/localeconv">localeconv</a></span>. The members of <code>lconv</code> are values of type <span class="t-c"><span class="mw-geshi c source-c"><span class="kw4">char</span></span></span> and of type <span class="t-c"><span class="mw-geshi c source-c"><span class="kw4">char</span><span class="sy2">*</span></span></span>. Each <span class="t-c"><span class="mw-geshi c source-c"><span class="kw4">char</span><span class="sy2">*</span></span></span> member except <code>decimal_point</code> may be pointing at a null character (that is, at an empty C-string). The members of type <span class="t-c"><span class="mw-geshi c source-c"><span class="kw4">char</span></span></span> are all non-negative numbers, any of which may be <span class="t-lc"><a href="../types/limits.html" title="c/types/limits">CHAR_MAX</a></span> if the corresponding value is not available in the current C locale.

The characters of the C-strings pointed to by <code>grouping</code> and <code>mon_grouping</code> are interpreted according to their numeric values. When the terminating <span class="t-c"><span class="mw-geshi c source-c"><span class="st0">'<span class="es5">\0</span>'</span></span></span> is encountered, the last value seen is assumed to repeat for the remainder of digits. If <span class="t-lc"><a href="../types/limits.html" title="c/types/limits">CHAR_MAX</a></span> is encountered, no further digits are grouped. the typical grouping of three digits at a time is <span class="t-c"><span class="mw-geshi c source-c"><span class="st0">"<span class="es5">\003</span>"</span></span></span>.

<p>The values of <code>p_sep_by_space</code>, <code>n_sep_by_space</code>, <code>int_p_sep_by_space</code>, <code>int_n_sep_by_space</code> are interpreted as follows:
